Im going back to standard airbox but has no plans to cut the resonators out, i have just bought an rrc intake manifold to hopefully make it super responsive.Bonson said:The Mugen airbox is just an eye candy in my opinion. If you want a quick respond (low down to mid range) power, a modified OEM airbox is the way forward with minimum spending. I made some modifications on my brother's EP3 airbox as follows;
Then we done a test comparison against my dc5 (when it was standard apart from Mugen airbox) on the local 1/4 mile drag strip. The results was very surprising! His EP3 was able to pull a wheel length in front of me every run untill we got to 60-70mph and than my dc5 would slowly pull ahead to the finishing line. We did about 5 runs and it the result was very consistent.
- Cut the intake hose to widen the hole to take air from the front rather than from the side (next to the battery)
- Removed and smoothen all resonant fins inside the airbox.
- Covered the entire air box with Foil wrap/tape (from DIY store) to lowered the intake temp
Even from this day he is still refuses to replace it with any other induction kit even though i offered him a Gruppe M for a Christmas present.
Mind if I ask why?Mark_teg said:I've gone back to OEM airbox after using a Gruppe M for about 4 years.. Don't miss it at all!
I wanted a change.poeter said:Mind if I ask why?
Are there similar things you can do the Mugen intake like you do with the OEM? dunno if thats a totally daft question lolBonson said:The Mugen airbox is just an eye candy in my opinion.

The Mugen intake takes its air feed from the front grill so nothing you can do there either.
So am i right in saying half pointless in getting a Mugen intake without the Mugen front bumper? i noticed that has a hole in the front for air feed.Teegwa said:The scoop feeds from the front as mentioned, I removed 3 x circles from the grill top to allow extra air flow.
Also have the SFS silicone hose coming ready to fit.
I wouldnt say pointless as you would still get "an" airfeed to the box, the other option is the 5zigen scoop you can get, Firthy who used to be on here used one and got some pretty decent results from it tooSylar122 said:So am i right in saying half pointless in getting a Mugen intake without the Mugen front bumper? i noticed that has a hole in the front for air feed.
